π-Conjugated semiconductors, primarily composed of elements with low atomic number, are regarded as promising spin-transport materials due to the weak spin-orbit coupling interaction and hence long spin relaxation time. Moreover, a large number of additional functions of organic semiconductors (OSCs), such as the abundant photo-electric properties, flexibility, and tailorability, endow the organic spintronic devices more unique properties and functionalities. Particularly, the integration of the photo-electric functionality and excellent spin transport property of OSCs in a single spintronic device has even shown great potential for the realization of spin manipulation in OSCs. In this review, the application of OSCs in spintronic study will be succinctly discussed. As the most important and extensive application, the long-distance spin transport property of OSCs will be discussed first. Subsequently, several multifunctional spintronic devices based on OSCs will be summarized. After that, the organic-based magnets used for the electrodes of spintronic devices will be introduced. Finally, according to the latest progress, spin manipulation in OSCs via novel spintronic devices together with other prospects and challenges will be outlined.
π共轭半导体主要由低原子序数元素组成，由于其自旋轨道耦合相互作用较弱，因此自旋弛豫时间较长，被视为很有前景的自旋输运材料。此外，有机半导体（OSCs）具有大量其他功能，如丰富的光电特性、柔韧性和可定制性，赋予了有机自旋电子器件更独特的性能和功能。特别是，将OSCs的光电功能和优异的自旋输运特性集成在单个自旋电子器件中，甚至为实现OSCs中的自旋操控展现出了巨大潜力。在这篇综述中，将简要讨论OSCs在自旋电子学研究中的应用。作为最重要且应用最广泛的方面，将首先讨论OSCs的长距离自旋输运特性。随后，将总结几种基于OSCs的多功能自旋电子器件。之后，将介绍用于自旋电子器件电极的有机基磁体。最后，根据最新进展，将概述通过新型自旋电子器件在OSCs中进行的自旋操控以及其他前景和挑战。
